Adrian hopes that his new training methods have improved his batting average. Before starting his new regimen, he was batting 0.5750.575 in a random sample of 8080 at bats. For a random sample of 4040 at bats since changing his training techniques, his batting average is 0.7500.750. Determine if there is sufficient evidence to say that his batting average has improved at the 0.010.01 level of significance.
